【摘要】 现代电网建设的快速发展,电力线载波通信扮演着非常重要的角色。作为电力系统的关键通信技术手段,不同厂商和用户对系统性能要求的不断提高再加上其他通信技术的竞争,因此必须要采用新技术来解决这些实际问题。本文结合已实现的基于DSP与FPGA的全数字电力线载波机,提出一种多路电力线载波通信系统解决方案,进而提出一种基于FPGA的多路复接器的设计实现方案。文章首先分析了典型数字复接系统构造及其实现方法,接着研究了复接器中的核心技术原理。其次,着重讨论了复接系统的硬件设计方案,采用模块的思想对主要结构单元的电路设计以及调试方案进行了分析与研究。本文设计的语音数据复接器主要用于在电力线载波机传输话音与远动数据。在借鉴已实现的模块电路的基础上,增加了以太网传输接口等功能,更能满足实际电力工程的需要。
【Abstract】 The rapid development of modern power grid construction, power line carriercommunication plays a very important role. Communications technology as a keymeans of electric power systems, different vendors and users on the system performancerequirements continue to increase coupled with competition from other communicationtechnologies, it is necessary to adopt new technologies to solve these practicalproblems.This paper has been implemented based on DSP and FPGA digital power linecarrier, proposes a multi-channel power line carrier communication system solutions,and thus presents a FPGA based multi-channel multiplexer design implementation. Thearticle first analyzes the structure of a typical digital multiplex system and itsimplementation, and then study the core technology in principle multiplexer. Secondly,focused on the hardware design of multiplexing system, using ideas module circuitdesign and debugging programs on the main structural units are analyzed and studied.This design of voice and data multiplexer is mainly used in power line carrierremote transmission of voice and data. In reference module circuit has been realizedbased on the increase of Ethernet transmission interface and other functions, to bettermeet the needs of the actual power engineering.
